Logic macroprogramming paradigms for wireless sensor networks (WSNs) are rule-based abstractions for programming a network as a whole. Programmers only focus on the main objective of the network rather than the low-level implementation details on each nod... see more

A composite specimen interface-cracking (CSIC) test was developed to evaluate the effect of the characteristics of the interface between asphalt layers on resistance to top-down and reflective cracking. The system involves repeated tensile loading and mon... see more

Elastic Recovery (ER) is used by many highway agencies for modified bitumen grading specifications. The current ASTM/AASHTO standards for ER testing utilize the ductility bath as the measurement apparatus. A new procedure for measuring the elastic recover... see more

One of high efficient ways to reuse the recycled construction and demolition waste (CDW) is to consider it as a road base material. The recycled CDW however is mainly a mix of recycled masonry and concrete with a wide variation in composition. This result... see more

On runway pavements in Japan, grooves for transverse directions should be set on most of runway area. The aim of runway grooving is to drain rain water on surface, which prevents from hydroplaning. According to the specification of Japan, two months as a ... see more

Moisture ingress is a primary catalyst for pavement damage and plays a key role in the performance of pavement materials in service. Moisture intrusion eventuates to early development of deficiencies (potholes) due to "pumping" effects and reduced effecti... see more
