Is there any correlation between unrepetitive plate loading test (aastho t235 or astm d1195) and repetitive plate loading test (din18134).

In our project, for construction of crushed stone base layer the constituent aggregates are silicate but the constituent aggregates of first asphalt layer are carvonate. What type of emulsion we must apply, anionic or cationic?

In our project, supervisor wants to test waterproofing system on bridges(adhension of bitumen membrane and concrete) according to standard en13596, in situ in one of constructed bridges. But i think in this standard the test must take place in laboratory with specific conditions. Is any other...

thread367-240839 Does anyone has experience of micro-cracking technology, for cement stabilization base layer to avoid cracks?

Hi, i would like help to solve this issue. I have 78000 m^3 compacted soil (gravel and sand)from river deposit (embankent construction). Max Density 2,2 t/m^3 and loose density 1,67 t/m^3. I would like to find the uncompacted material that we excavate from borrow pit. Thanks

Hello i would to ask if anybody knows about correlation between sand equivalent and plasticity index for soils. In Serbia there is a standard(JUS U.B1.040) that writes: if EQS=0% soil full in clay if EQS=100% soil without clay if EQS >30 % soil no plastic ? If EQS<20% soil plastic ? Thank you

In our project, is used to asphalt wearing course bitumen 50/70 percantage 5.6% in agr. and as additive natural bitumenin percentage 8% in bitumen.This natural bitumen has melt point >180 celcious, asphaltene content more than 50% (rest sand) and is added in the mixer. my question, whta...

Hi i have one problem with Marshall values in asphalt mixes. I have all the values of the mix desigh very good except the Marshall flow. The strange is that the stability values are very good but the flow values out of limits. The aggregates are all crushed limestone and the bitumen content 4,0%...

We have in our specifications for the asphalt works the value marshall rigidity. This value is the result of Marshall stability/ flow and must be more than 250 for base course and more than 300 for binder. Because is the first project that we must check this value could somebody to give me more...

is there any correlation between plate bearing test and compaction test (cone method or with troxler)?

What ia the difference in the plate bearing test between method cnr-146, astm d1195, and bs1397.

how can i calculate the bulk factor for a crushed limestone max40mm (used as base layer in road construction)with bulk specific gravity 2,67 and maximum dry density 2,3 t/m3
