27、1IntroductionConcrete parking lots have many similarities to other typesof concrete pavement. On the other hand, parking lots differfrom other pavements in that most of the area is intended forstorage of vehicles and other goods rather than for movementof vehicles. The design of concrete parking lot

28、s should followgenerally accepted procedures for concrete pavements asoutlined in this guide. Load-bearing capacity, drainage, crackcontrol, life-cycle cost, constructibility, and maintainability areother characteristics that are important in the design andconstruction of concrete pavements, includi

29、ng parking lots.Typically, concrete parking lots do not serve the same broadspectrum of traffic loading, from light vehicles to heavytrucks, as highways and arterial streets. Facilities designed toaccommodate both light vehicles and heavier delivery trucksmay employ traffic controls to separate and

30、channel theheavier trucks away from areas designed for automobiles andlight trucks. Facilities designed for heavier vehicles are likelythose facilities where relatively accurate predictions of vehiclesizes and numbers are possible. Facilities intended to serveonly light vehicles may have concrete pa

31、rking lot slabs withthicknesses influenced by the practical limitations of thematerial and environmental effects rather than by the pavementstress created by vehicle loads. Durability-related distress isoften the most critical maintenance concern for lightly loadedconcrete parking lot pavements, whi

32、ch are subject to theeffects of fuels and lubricants leaked from vehicles as well asenvironmental influences. Vehicles in parking areas usuallytravel at low speeds, diminishing the importance of smoothnesstolerances. Because parking lots must also accommodatepedestrians, designs and geometrics shoul

33、d reflect pedestriansafety considerations including crosswalks, a slip-resistantsurface texture, and nighttime illumination.Concrete parking lots range in size from small, such as atcorner convenience stores, to medium, such as at multi-unithousing projects, to large, such as those for shopping cent

34、ersand office or commercial developments. Most parking areasinclude driveways, some of which need to accommodaterelatively heavy loads. Special consideration may be neededif access to dumpsters is to be included. Accordingly,concrete parking lots are constructed with a wide variety ofconstruction eq

35、uipment, ranging from hand tools and vibratoryscreeds to large highway paving equipment or laser screeds.Because of the relatively high stiffness of concretepavements, loads are spread over larger areas of the subgradecompared with asphaltic pavements. As a result, thinnerconcrete pavements can be u

36、sed for the same subgrade material.Additional benefits of using concrete to construct parkinglots include the following:Concrete surfaces resist deformation from maneuveringvehicles;Concrete surfaces drain well with only minimal slopes;Concrete has relatively simple maintenance requirements;Traffic

37、lane and parking stall markings can be incorpo-rated into the jointing pattern;Concrete is minimally affected by leaking petroleumproducts;The light-reflective surface of concrete can be efficientlyilluminated with minimal energy requirements; andConcrete parking lots reduce the impacts of the urban

38、heat island effect relative to those of asphalt parkinglots by producing lower surface temperatures, thusproviding a cooler urban environment and reducingozone production.DESIGN AND CONSTRUCTION OF CONCRETE PARKING LOTS 330R-3The sustainable construction benefits of concrete areconsiderable as compa

39、red with other pavement materials.Concrete parking lots typically have service lives of 30 yearsor more, requiring no additional use of aggregates and othernonrenewable materials resources through the period. Inaddition to opportunities for the use of sustainable concretecomponent materials such as

40、recycled aggregates and supple-mentary cementitious materials derived from industrial by-products, concretes light-colored surface helps reducereflected solar radiation, and its higher reflectivity canreduce illumination requirements considerably. Lowerresulting energy requirements are realized thro

41、ughout thefacilitys life cycle. Pervious concrete may be useful inreducing storm water runoff from the site (ACI 522R). At theend of the service life, concrete can be recycled into aggregatesand pavement subbase materials. These and other attributesof concrete can be useful in obtaining LEED Green B

42、uildingcertification for a project (Portland Cement Association 2005).1.2ScopeThis guide is based on the current knowledge and practicesfor the design, construction, and maintenance of concreteparking lots. It emphasizes the aspects of concrete pavementtechnology that are different from procedures u

43、sed to designand construct other types of slabs-on-ground, such as streets,highways, and floors. This guide is not a standard or aspecification, and it is not intended to be included by referencein construction contract documents. ACI 330.1 can be usedfor these purposes.Parking lots have most loads

44、imposed on interior slabssurrounded by other pavement, providing some edge supporton all sides. Highway and street pavements carry heavyloads along and across free edges, and are subjected togreater deflections and stresses. Streets and pavements areusually designed to drain toward an edge where the

45、 watercan be carried away from the pavement. Parking lots areusually designed so some of the water is collected internallyand is conveyed away through underground systems. Inurban areas where rainfall runoff from large impervioussurfaces is regulated, parking lots often serve as detentionbasins (not

46、 addressed in this guide). This means that thepavement should store water for a period of time withoutincurring any damage due to loss of support from a saturatedsubgrade. Parking lots often accommodate appurtenances,such as lighting standards, drainage structures, trafficislands, and landscaped pla

47、nting areas. Provisions for theseappurtenances should be considered in the design of thejointing system and the layout for construction.1.3BackgroundDesign methods for concrete parking lot pavements aresomewhat empirical, and are based on the methods developedfor the design of highway pavements such

48、 as the PortlandCement Association (1984a,b) method and the AASHTO(1993) design method. These methods are primarilyconcerned with limiting both the stresses in the slab and thereductions in serviceability caused by mixed traffic,including heavy trucks, whereas parking lots usually servefewer vehicle

49、s either parked or traveling at slow speeds. Formany parking lots that will serve only light traffic loads, theneed for an extensive design process may be less critical. Forsuch projects, a designer can rely on personal experience toselect conservative values for the design criteria of subgrade soilsupport and imposed vehicle loads. In these cases, a conservativeselection of pavement thickness is prudent practice.Determining and specifying practical thickness tolerancesfor pavements is critical. Reduction of the pa
