Pavement Concrete

Because of some drawbacks including low strength, poor dimensional stability, low abrasion resistance, easy to crack and other shortcomings, Portland cement concrete was limited to use as a dominant pavement material in highway construction. This paper studied the feasibility of making high performance pavement concrete by adding 20-40% of high-quality composite ultra-fine fly ash (CUFA) technology to achieve high-performance of concrete roads have been studied. The test results indicated that: with cementitious material content of 360~400 kg/m3 and CUFA content of 20% ~ 40%, adding CUFA improved the workability of concrete significantly; in the meantime, the 28d compressive strength was as high as 50 MPa, and the later strength of concrete continued growing. The designed concrete satisfied the requirements of opening to traffic after 3 days after the construction and heavy and extra heavy traffic in 28 days. The durability, especially the abrasion resistance, and the crack-resistance were improved significantly. The designed pavement concrete not only had a good compressive performance for practical engineering but also had good technical, economic, social and environmental benefits.

Differentiated Service

Diffserv-aware and Traffic Engineering combine the advantages of MPLS, Traffic Engineering (TE) and Differentiated Services (Diffserv, DS) to provide high performance and Quality of Service(QoS) in networks. We have designed three scenarios on Juniper Networks platforms to analyze the packet loss rate and delay for video, voice and data. The results show that MPLS DS-TE can improve the QoS for differentiated service effectively. The research has practical value for the development of DS-TE based on MPLS.
