Partial Depth Reclamation with Expanded Asphalt Mix [PDR-EAM] Method Specification 2018. companion samples collected before and after the addition of expanded asphalt. Samples of Expanded Asphalt Mix will also be tested for bulk density, maximum theoretical density, and air void content.
Uniformity and balance are best ensured by careful preparation. Materials are required to be sampled and tested and plant components carefully inspected and calibrated before production begins. COLD AGGREGATE STORAGE AND FEEDING The cold aggregate feed is
SUPERPAVE MIX DESIGN METHOD The Superpave mix design method is a volumetric mix design process. An analysis of specimens and the maximum specific gravity sample are conducted to evaluate such properties as voids in mineral aggregate (VMA), voids filled with asphalt (VFA), air voids, and the dust/effective binder ratio.
This method is used for the design of asphalt mixes which contain reclaimed asphalt pavement , Cn105623279A Method For Preparing Blended Asphalt Method T312 Preparing and Determining the Density of Asphalt Mixture Specimens by Means of , Cn105623279A Method For Preparing Blended Asphalt the RAP and/or RAS will mix with the virgin asphalt binder to produce a final blended binder.
In general, these laboratory test results support the results of the field study which showed that there was no difference in overall field performance between the SEA and AC sections (4). Many of the reasons in the 1970s for considering sulfur as an alternative binder source also exist today.
Asphalt Mortar Testing: Two mortar samples are tested: Single sized RAP material (typically passing #50 and retained on #100 sieve) Disadvantages: May not be representative of the actual fine aggregate proportion in a full mix Often limited to low percentage of RAP or RAS due to workability concern.
