Significance and Use4.1 This test method is used with Methods A and B of TestMethods D 698 to develop relationships between moisturecontent

9、, density, and penetration resistance. These relationshipsare used with a previously prepared family of moisture-penetration curves as a rapid field test to determine theapproximate amount of moisture in the soil.NOTE 1When a penetration-resistance measurement of material inplace is compared at a gi

10、ven moisture content with penetration-densitycurves prepared at a specified compactive effort, an approximate check ofcompaction (density) may be obtained.4.2 Penetration resistance determinations are not reliable forvery dry molded soil specimens or very granular soils.NOTE 2Notwithstanding the sta

11、tements on precision and bias con-tained in this standard, the precision of this test method is dependent onthe competence of the personnel performing it and the suitability of theequipment and the facilities used. Agencies that meet the criteria ofPractice D 3740 are generally considered capable of

12、 competent andobjective testing. Users of this test method are cautioned that compliancewith Practice D 3740 does not in itself assure reliable testing. Reliabletesting depends on many factors; Practice D 3740 provides a means ofevaluating some of those factors.5. Apparatus5.1 Moisture-Density Appar

The set of interchangeable needles shall include thesizes given in Table 1. The needle shank shall have gradu

18、ationsinscribed at intervals of12 in. (10 mm) to indicate the depth ofpenetration, and shall have a length of not less than 4 in. (100mm), excluding the threaded portion. Needles should not beused when they have been worn so as to reduce the flat-endarea by 5 %.5.4 Balance or ScaleA direct reading p

20、e No. 4 (4.75-mm) sieve shall have at least 20 %passing the No. 200 (75-m) sieve.7. Calibration7.1 The penetrometer may be calibrated by measuring theload applied by means of a platform scale. Apply loadingmanually using the needle directly on the scale so that thespring compresses at a rate of appr

21、oximately12 in. (10 mm) persecond to13 of the full range of the penetrometer scale. Readthe loading on the platform scale. Repeat the test at23 and thefull range of the penetrometer scale. The difference, if any,between the penetrometer and the scale or balance should notexceed 2 lbf (8.89 N). For e

22、ase in calibration, it is recom-mended that the 1-in.2(64.5-mm2) needle be used.7.2 The penetrometer should be cleaned, lubricated, andcalibrated on a regular basis. The penetrometer should bestored in a clean location or case, with no compression on thespring.8. Procedure8.1 Compact the soil in the

23、 moisture-density mold in accor-dance with the procedure described in Method A or B of TestMethods D 698.8.2 Determine the resistance of the soil to penetration by useof the soil penetrometer with attached needle of known endarea. The needle used shall be of such size that the readingsobtained will

24、be between 20 and 80 on the decimal scale or 10and 40 on the metric scale. Place the mold containing the soilspecimen on a smooth space between the feet of the operator.The operator shall hold the penetrometer in a vertical positionand shall control the rate of penetration by steadying the armsagain

25、st the front of the legs at the same time applying pressureto the penetrometer handle (Note 2). Penetrate the soil speci-men at the rate of 0.5 in. (13 mm)/s for a distance of not lessthan 3 in. (76 mm). Place the penetration needle away from theedge of the mold (approximately four times the needle

26、diam-eter), near the center, and space the individual penetrations soas not to interfere with one another. Penetrate the soil specimennot less than three times and use the average of the readings.NOTE 3With some large penetrometers, it is difficult to use the devicein the manner discussed in 8.2. Th

27、erefore, the operator should hold thepenetrometer in a comfortable vertical position that yields a steady rate ofpressure application.8.3 Determine the penetration resistance on each moldedsoil specimen as described in 8.2.9.
