Fly-ash is an industrial waste burning pulverize coal boilers for thermal power plant and large enterprises, the steel slag is too a residue generated waste in steelmaking industrial processes, the average for every ton steel to produce half ton steel slag, steel slag and fly ash discharge amounts is very big, utilization ratio is very low. At present, a large number of steel slag is used of reclamation work, the remaining items is used rarely and large number is left storage. This paper is introduction steel slag and fly ash to do road base-course material, such can make good use of industry residue waste in large amount to reduce exploitation and cut down natural building stones, it is an application for ecological building materials again. Major study the steel slag and fly ash road features, these tests include materials compaction reality among them, mix design, unconfined compressive strength, split tensile strength, resilient modulus and other commonly used performance. Through comparative analysis, this two materials combination has good use of quality, it has greatly better than other materials such as lime-fly-ash stabilize crushed stone and lime-fly-ash soil and other materials. In particular, it has very good performance to reduce road base-course crack, the material has good resistance shrinkage and temperature shrinkage ability. Therefore, the combination of steel slag and fly ash can be done entirely road base-course and extend the road life.

The amount of data transmission in Electronic commerce (E-commerce) is growing, and the security requirements are also increasing. During the data transmission , the data transmission module is divided into four parts, They are respectively: the Internal network, isolation module, firewall and the untrust domain or external network. At the isolation module, the exchange isolation unit, data transmission unit, file transfer unit, and other units and engines, are set. The security is enhanced in e-commerce in many ways, the large flow of data transfer between different trust domains.

Transmission of traffic in optical network, the network may interrupt transmission because some component failures. In order to avoid such things, and in order to ensure a reliable business streaming, we proposed an algorithm to improve the service quality of the optical network. This algorithm is that some links used the protected road in the optical network link. In addition, this algorithm also supports traffic grooming. By this algorithm, the success rate of the users establishing a connection can be improved, and the quality of service of the network can be ultimately improved.
