This technological measure is that CCCC Xi'an Road Construction Machinery Co., Ltd. undertakes the reconstruction and expansion of Changjin.SSZ1. During construction of standard water-stabilized base course，Splicing of water-stabilized base of new and old roads for reconstruction and expansion project，Quality inspection: water-stabilized rolling at the overlap of coring is loose.、Poor compactness、Difficult to bond the old and new pavement into a whole，This is the biggest problem in the widening construction of water-stabilized base pavement.，Changjin Project Department of CCCC Xizhu Pavement Engineering Branch will discuss the difficulties in production and operation、Blocking Points Become Innovative Topics，Actively explore，Be bold in innovation，Based on construction site safety、Quality、Work efficiency and other requirements，Organize young technicians to carry outQCTackle key problems，Communicate through learning、Comparative experiment，Cleaning and flushing—Apply cement cake—Edge cloth—Automatic grouting—Edge pressure compensation—Artificial pulp supplement“Six-step method”Craft，It effectively improves the construction quality of the joint between the old and new roads.，Remarkable results have been achieved through experiments and popularization.。

The proposal of this construction technology measure is one year since the establishment of CCCC Xizhu Pavement Engineering Branch.，Carry out continuously“Five small”Innovative activities，Excavate、Incentives、Cultivate innovative talents，Focus on fostering an innovative cultural atmosphere，Continuous cultivation of innovative talents，Export innovative achievements，Encourage young employees to tackle key problems based on their posts，Achievements in innovative and effective work。These activities are carried out to promote the construction of high-quality projects of the company.，Promote the production and management level of construction projects to further improve，To play a greater role in promoting the company's high-quality development。
