Comprehensive investigation of using tire-derived aggregate in chip seal subjected to various traffic and environmental conditions
<p>"Chip seal is one of the most cost- and performance-effective pavement preservation treatments commonly used in the United States. Using crumb rubber obtained from scrap tires as a partial or full replacement for mineral aggregate has been proposed as a sustainable solution to reduce the …

Quality Assurance for Chip Seals Using Mean Profile Depth
Chip sealing has numerous benefits as a pavement preservation treatment. The quality of the chip seal is assessed through various parameters, including texture depth, skid resistance, and visual evaluation. Current practice reveals that transportation agencies conduct quality assurance after …

The development of a thermoplastic road marking material standard
… road markings. On clean roads, both asphalt and chip seal surfaces, thermoplastic road marking materials have longer RL and Qd service lives than water-borne road marking paints. The white road marking paints and materials generally complied with the colour specification. However, the yellow road …
