The new abrasive iscurrently more aggressive, resulting in lower Havalues than when the standard was initially established

21、. As such, care should be taken when interpreting Hatest results,both with regard to this standard and with regard to historical data from the same quarry source. Committee C-18 is actively studying alternatives to deal with this issue.CAbrasion Resistance Test Method C 1353 will eventually replace Test Method C 241 and it is not necessary to perform both tests. Availability of the proper equipmentand materials by the testing laboratory may determine which test is performed.DNot recommended for paving in areas subject to heavy foot traffic.C616032
