Gradation and Size – Pavement Interactive

Maximum aggregate size can affect HMA, PCC and base/subbase courses in several ways. In HMA, instability may result from excessively small maximum sizes; and poor workability and/or segregation may result from excessively large maximum sizes (Roberts et al., 1996). In PCC, large maximum sizes may not fit …See more on pavementinteractive

Why do you need an aggregate base under your asphalt?

The simple answer is the asphalt alone is not strong enough to support the weight of vehicles. Why is an aggregate base important? There are two main purposes of an aggregate base. One is to offer a foundation to allow larger loads to travel on the pavement. The other is to give a frost barrier to prevent heaving when the temperatures …
