1. Interfacial bond-slip relationship between Carbon Fiber Reinforced Polymer Plate and Concrete after High Temperature of Asphalt Paving Construction
Abstract The bond-slip relationship of Carbon Fiber Reinforced Polymer (CFRP) plate-concrete after the influence of high temperature action of Stone Mastic Asphalt (SMA) paving was investigated in this article. Two groups of double shear specimens with different bonding length were designed and tested. Based on the test results, the failure modes of specimen

2. Análises de dosagens de concreto asfáltico do tipo Pré Misturado a Frio (PMF) utilizando Resíduos da Construção e Demolição de obras (RCD)
RESUMO Na construção civil, um problema ambiental recorrente é a geração e disposição de Resíduos de Construção e Demolição (RCD) de obras. A utilização do RCD como agregados na composição de concreto asfáltico, do tipo Pré Misturado a Frio (PMF), torna possível a execução de pavimentos rodoviários de baixo tráfego. Diante desses fatos

8. Comparison between the field performance of CAP 30-45 and CAP 50-70 for pavement layers. / Comparação do comportamento em campo de concretos asfálticos com CAP 30-45 e com CAP 50-70 para revestimentos de pavimentos.
In the last years, the volume of commercial heavy vehycles that transit through Brazilian highways is increasing. In addition, pavement wearing courses are exposed to the influence of high temperatures, that cause precocious asphalt layer distresses Therefore, asphalt mixture alternatives to the high traffic higwayshave been studied. One of the possibilities
