1 Intelligent Compaction Workshop Hosted by ISAP 2012 Supported by US FHWA 8:30AM to noon, May 22, 2012, Nanjing, China Background Intelligent compaction (IC), also known as Continuous Compaction Control (CCC), is an evolving technology to maximize the compaction effort using vibratory rollers that equipped with roller-integrated measurements, global positioning system, onboard report system, and, optionally, auto-feedbacks. The IC technologies are proven and demonstrate immediate benefits to agencies and contractors alike. For heavy duty asphalt pavements, IC can be used to provide adequate compaction in order to optimize asphalt densities for supporting heavy loading. This workshop will guide the attendees along the shortest path to IC implementation by overcoming gaps and barriers through streamlined strategies. Purposes Familiar attendees with fundamentals of intelligent compaction Demonstrate real world applications of IC Demonstrate latest IC machines and systems Demonstrate the shortest route to successful IC implementation.

27 Session 2 Sakai IC System QC/QA Method; IC vs. Conventional IC collects 100 % of compaction data in rolling area. Conventional QC/QA compaction criteria: Limited number of cores and/or (nuclear) density gauge. Method Frequency Remarks China Core sampling 3 cores/2000 m 2 with Marshall density 97% or 94%Gmm. Final verification is 5 cores/km/direction with represented Marshall density 96% or 92% with 95% confidence Japan Core sampling 1core/1,000 m 2 USA Core sampling or Nuclear gauge 1 core/150m or 500t Stratified random sampling UK Indirect density gauge Core sampling 20m intervals 1core/1,000 m 1core/250m BS594987, at wheel-tracks 100 mm from unsupported edge Australia Core sampling or Nuclear gauge 1 core/30t or homogeneous section IC Demo in GA, USA 09 IC roller on GAB subbase, and HMA application High Density, but Low CCV?? Density level achieved was almost higher than 92%. But, CCV decreased with an increase of the density. Sakai CCV (%) Required TMD: 92% y = x R 2 = Gmm% 14

28 Session 2 Sakai IC System Depth of CCV Measurement CCV measures all the mechanical properties for three underlying layers of 0.6 m in depth from the surface. Soft subgrade with high moisture content lowered the stiffness and CCV measured on HMA pavement. HMA Pavement High Density? Low CCV Depth of CCV measurement: 0.6 m Aggregate Subbase Soft Subgrade with high moisture content Low Stiffness Do You Like This Pavement? A key to construct durable and long lasting HMA pavement is to construct stiff underlying layers. Conclusions Sakai CIS is the proven IC Technology for HMA pavement. CIS is helpful to construct durable pavement, because it improves; (1) Uniformity of Roller pass, (2) Compaction temperature of asphalt pavement, (3) Speed of QC/QA by real time measurement, and (4) Accuracy of QC/QA by a 100 % of CCV proof-rolling. Paving contractors can save fuel, money and time by eliminating useless roller passes. Next steps to move forward; (1) Training for highway agency and paving contractors. (2) Justify the initial investments. Durable HMA pavement needs to be constructed over stiff underlying layers such as subbase and subgrade. 15
