Moisture sensitivity testing for asphalt strippingStripping is the loss of adhesion between bitumen and aggregate when water enters an asphalt pavement. The damage may stay hidden until traffic pumps moisture…Elastic Recovery of Asphalt Mixtures After Repeated LoadingUP. PPP is the technical testing and measurement unit operating under Jakarta’s Dinas Bina Marga public works department. It provides accredited laboratory and…Determining optimum binder content by Marshall mix designOptimum binder content (OBC) is the amount of bitumen that gives a Marshall asphalt mixture the best balance of density, air voids, aggregate space and…Bond Strength Testing for Overlays on Exposed ConcreteUP. PPP is a technical testing and measurement unit operating under Jakarta’s Dinas Bina Marga public works department. It provides accredited laboratory and…How the Los Angeles abrasion test predicts pavement surface wearAggregate is the load-bearing skeleton of asphalt. Under traffic, grains at the surface fracture, abrade and shed fines, gradually changing a stable pavement…Fiber Reinforcement and Flexural Toughness in Concrete OverlaysConcrete overlays are thin cementitious layers placed over existing slabs, bridge decks, and pavement surfaces to restore protection, level, or ride quality.…Flash Point Testing for Safer Asphalt Emulsion HandlingAsphalt emulsions are widely used on Australian road projects because they bind aggregate without requiring the temperatures associated with hot-mix asphalt.…Downhole seismic testing for bridge foundation stratigraphyUsing downhole seismic testing to characterise soil stratigraphy for bridge foundations gives engineers a measured view of how ground stiffness changes with…Vebe Time Testing for Slipform Concrete WorkabilitySlip forming puts fresh concrete under a demanding combination of movement, placement and rapid consolidation. The form is raised as earlier concrete stiffens,…Chemical Stability Testing for Aggregates in Asphalt MixturesAggregate is the mineral skeleton of an asphalt mixture. Its particles carry traffic loads, interlock under compaction and help the pavement resist rutting,…
