Provincial Jiuquan Highway Business Development Center Test Testing Room: Be a good "four new technology" customs officer

The newspaper is aimed at the current status of uneven quality of sewing glue. Recently, the test and testing room of the Jiuquan Highway Business Development Center of Jiuquan Highway Division has sampled the sampling of the seams purchased by the maintenance units.After repeated comparison tests, the cement mortar block independently developed by the center can replace the cement concrete block as a connection block with the sealing colloidal in a low temperature stretch test to solve the sealing colloid and the adhesion of the connecting block during the low temperature stretch test process of the irrigation gum.The problem of adverseness provides technical support for the sealing test, which guarantees the implementation effect of asphalt pavement sealing gel seams.
