Based on findings from the literature review, laboratory tests, and pavement performance
simulations, researchers concluded that the use of reclaimed asphalt pavement (RAP) in Portland
cement concrete (PCC) is largely feasible for the pavement application. Despite the fact that
RAP-PCC yielded reduced mechanical properties (especially different strengths), a proper
utilization of optimized aggregate gradation benefits from using RAP and the use of RAP-PCC
as a bottom lift in a two-lift pavement construction can compensate the strength reduction and
allow more RAP in the mixture. An even higher amount of aggregates (both coarse and fine) can
be replaced to make full use of RAP to make low strength PCC for the other applications such as
curbs, gutters, sidewalks, etc. Considering the factors related to strength, materials, construction, and performance, researchers developed the following guidelines.
The purpose of this review was to measure the effects of No. 57 coarse aggregate gradation and segregation on the cement efficiency as measured by wor...
Two sections of pavement were built with different specifications for the gradation of the aggregates, one with the standard gap-graded aggregate spec...
