New method uses conventional equipment


X-900sROADTEC equipment to undertake the eradication of asphalt paving asphalt operations. 11 points that night, only one RP-190ROADTEC paver and a SB a 2500CROADTEC reciprocating feeder will all work completed. In the Paving, RP 190 Paver stopped at a newly paved road shoulder, and reciprocating feeder is stopped at the traffic lane, there is no truck in the new sub-base on the paved road. Interstate Highway was opened on Monday, the deadline is 5 o'clock in the morning, the final crossed operations, including roads. Georgia Department of Transportation with the contract stipulates that the job is in Atlanta on Interstate 75 north, about 102 miles of lanes for eradication, refurbishment and re-paved road. In the Commonwealth, Matthews committed projects from the 411 mountain road to a red roof. Contractor is the inside shoulder lane from the south began to work. 55 new ways to use conventional equipment Hou Chi Wang Shuhui small Georgia Department of Transportation to allow Matthews and APAC from Friday 8 pm to 5 am Monday morning traffic off the busy interstate highway in the lane. If the contractor's personnel or equipment to the required evacuation time is not road, will be severely punished. The company works on a strict supervision. They think that I-75 shoulder project as the contractor won a great honor . Planning stage doing pretty well perfect. Hou Chi Wang Shuhui compiled from the US Small published asphalt emulsion (sticky layer of emulsion) can increase the mixture layer of newly laid asphalt stabilization Treatment its lower layer, middle layer and link layer of the adhesive and the seams and the attachment structures, usually saturated with bitumen emulsion (PK-4) and mixed with rubber asphalt emulsion (PKR-T) and so on. In recent years, in order to adapt to the advancement and diversification of demand, is looking for a way of concern for the environment (prevent the asphalt layers of material wrapped around the stick, causing the pollution of the surrounding roads, etc.) and adapt to the thin layer of road surface drainage,christian louboutin pas cher, high increased porosity and other properties of the asphalt emulsion. Therefore, the development of improved emulsion has the following characteristics. ① the construction machinery can inhibit the adhesion of tires. ② extraordinary adhesion. 1.2 Test results 1.2.1 of construction machinery tires attached to the inhibitory effect of improved emulsion adhesion inhibitory effect on the tire (non-adhesion),franklin marshall paris, according to the spreading emulsion, the dump truck wrapped around the stick without moving, stripped to judge. Improved emulsion did not find the tire adhesion and drawing, so that is able to fully inhibit the adhesion of tire material. Moreover, the interior volume of tire adhesion of emulsion numerical results show that improved tire adhesion on the amount of emulsion is PK-4 1 / 7, PKR-T 1 / 5, to confirm the inhibitory effect of bonding. 1.2 .2 Improved emulsion adhesive tensile bond strength tests, shear test results show that compared to PK-4, PKR-T, improved emulsion adhesive strength stronger. 2 on the spread in the open-graded asphalt pavement surface can inhibit the function of the asphalt emulsion aggregate flying characteristics and effects of the first 56, the modified asphalt emulsion described the development process. Along with traffic safety and low noise requirements, drainage of the road lay the object is from the highway trunk roads and city streets to the parking lot expansion . However, the major transport routes and repeated the role of solid cut and other effects of the harsh conditions, everywhere flying drainage of road aggregate, road repairs and potholes and other damage. To curb this road damage,franklin marshall femme, road surface drainage of spreading asphalt emulsion modified,birkenstock paris, by making it a strong film, you can maintain the original drainage performance, and increase the aggregate dispersion and abrasion resistance and other durability. 2.1 features improved asphalt emulsion of the following features. ① inhibit the aggregate effect of flying. ② the use of asphalt emulsion, resin system compared to the original emulsion, no smell. ③ Even after the laying of the surface, the surface temperature is high, leaving water in the case, you can immediately construction. 2.2 standard cross-section I modified asphalt Fu Shang [force 'method of standard vertebral Peng surface shown in Figure 1. Modified asphalt emulsion asphalt emulsion applied 1-r modified method of standard cross-section Figure 2.3 The results shown in Table 1 the specifications of the test specimen, the implementation of the various test results are as follows. Table 1 Test specimen specifications (layer 2) hard sandstone 0.15kg / m (layer 2) modified asphalt emulsion 0.35kg / m (level 1) hard sandstone 0.35kg / m (Layer 1) modified asphalt emulsion 0.35kg / m matrix mixture over drained mixture 13ram, 20% porosity
