Section III: Surface Gravel, base course Fines and Plasticity Index Notice also the difference in the fine material and the plasticity index (PI) While gravel surfacing allows 4% and up to 15% of the material to pass a #200 sieve, base course can have as little as 3%, but not more than 12% passing the same sieve More importantly, the PI can fall to 0 in baseCrushed Rock (1, 1-1/4" minus crushed rock, also known as crushed surfacing base course (CSBC), packs tightly and holds in place, making it the primary base material for heavily trafficked roadways CSBC also adds stability to bridges and muddy or wet areasAsphalt Concrete Base (ACB), Consider the original purpose of the crushed aggregate untreated base Sometimes aggregate base is needed to provide material to fine grade and to provide a smooth surface on which to pave In these situations, ACB should not be substituted for crushed aggregate untreated base Other ACB Information Compacted density is about equal to 185 ,Chapter 3 DIVISION 300, Base Course, Crushed 1A, B or C Subbase Course, Gravel 1D , Resident to determine the density When layers are constructed of differently graded aggregate, fine grading of the lower layer , Aggregate base course and aggregate subbase course designated by pay item to be measuredDensity of Common Building Materials per Cubic Foot, These values for density of some common building materials were collected from sites across the Internet and are generally in agreement with multiple sit Most are from BOCA or ASAE tabl However, if you have values that you believe are more accurate, use them for your calculations, and please send me an e-mail to let me know what your ,.
