The analysis is the part of the engineering tool for the bridge designers.
According to length and width of the slab, the engineer can easily choose the shear reinforcement diameter and its distribution.
Results from this analysis will be used for the creation of the engineering tool for design of the shear reinforcement of the reinforced concrete approach slab.
Preliminary Engineering Tool for the Sheer Reinforcement Design Inspiration for the creation of the engineering tool came based on actual design standard (OTN 73 6244 [1]), because the standard already contains the tool for the determination of bending moments and thickness of the slab according to its length in form of graph.

Study on testing the relative density of coarse aggregate by Vacuum Method instead of basket method LI Zhi1, a, and ZHU Feng1,b 1 Department of Civil Engineering, Shandong Jiaotong University, Jinan, Shandong 250023 aemail: lizhilj@163.com, bemail：sdzhuf@163.com Keywords: Vacuum Method; basket method, relative density of coarse aggregate; mixture design of asphalt mixture; highway engineering Abstract.
The bulk volume relative density Ri and apparent relative density Ri of different specification coarse aggregate in calculation formula are tested by basket method required by Engineering> (JTG E42-2005) T0304-2005.
So, if we test the relative density of coarse aggregate by vacuum method in stead of basket method , the test time will decrease to a great extent and the working efficiency will be raised, which has important significance for the engineering. 1.
Referring to the test methods (vacuum method) of maximum theoretical density of bituminous mixture in the Engineering> (JTG E20-2011).
The density of crushed stone of different specification selected in table 5 are tested by T0304-2005 coarse aggregate density and water content test methods(basket method) according to the Engineering>.
