Evaluation of polymer-modified chip seals at low temperatures

This paper compares the performance of chip seals constructed with polymer-modified emulsion (PME; CRS-2L) versus those constructed with unmodified emulsion (CRS-2). The overall performance evaluation is based on aggregate retention performance. The adhesion of the emulsions is examined using the Vialit test with various curing times and temperature conditions. To evaluate the aggregate retention performance of the chip seals, the authors used the Vialit test, the flip-over test and the third-scale Model Mobile Loading Simulator (MMLS3). The results from these tests indicate that the PME (CRS-2L) enhances aggregate retention performance, and does so more significantly in the early stages and at low temperatures.
