TESTING THE USE OF NON-DESTRUCTIVE INSPECTION OF BITUMINOUS ROAD SURFACINGS WITH RESPECT TO DENSITY AND THICKNESS
| 项目名称： | TESTING THE USE OF NON-DESTRUCTIVE INSPECTION OF BITUMINOUS ROAD SURFACINGS WITH RESPECT TO DENSITY AND THICKNESS |
| 摘要： | ON A LARGE CONSTRUCTION SECTION THE SECOND LAYING OF THE BITUMINOUS ROADBASE IS TO BE SUBJECTED FIVE TIMES PER CONTRACT SECTION TO ORTHODOX INSPECTION TESTING FOR DENSITY AND THICKNESS AS PRESCRIBED IN AUSTRIAN SPECIFICATIONS. DURING THE INCORPORATION OF THE MIXTURE SIX ALUMINIUM MEASURING FOILS ARE BEING GLUED ON AND SIX METAL SHEETS NAILED ON; THESE ARE FOR LATER MEASUREMENT OF DENSITY AND SHOULD HELP TO CLARIFY THE SORT OF MEASURING POINTS WHICH ARE BEST. AFTER INCORPORATION OF THE MIXTURE THE NON-DESTRUCTIVE INSPECTION TESTING IS CARRIED OUT BY 12 DIFFERENT LABORATORIES. ALL RESULTS ARE BEING STATISTICALLY EVALUATED WITH A VIEW TO ESTABLISHING THE OPTIMUM NUMBER OF NON-DESTRUCTIVE MEASUREMENTS NEEDED TO OBTAIN ACCURACY COMPARABLE WITH THAT OF THE ORTHODOX METHOD. |
