What's sort of "sidewalk" pavement is this?

The technical term for this (in the UK) is "deterrent paving" and its function is to discourage pedestrians, cyclists and drivers from being where they are not supposed to be. In the OP's photo, the ...

What is the influence of precipitation on pavement performance in both jointed plane concrete pavements (JPCP) and asphalt concrete pavements?

Erosion, frost heaving, and suction are all ultimately caused by precipitation on the pavement. Precipitation is used in the following models: The Enhanced Integrated Climatic Model (EICM) uses ...

What is the "allowable number of axle-load to failure equation" used in Pavement ME Design?

The allowable number of axle-load repetitions to failure, $N_f$ is used to calculate the incremental fatigue damage using Miner's law for each analysis interval (which is equal to one month, or two 15-...

Design Roller Compacted Concrete Pavement Section

Pavement ME does not have an RCC pavement design module so using it to design RCC is not within the bounds of the design procedure. If we are talking general pavement performance principles, there ...

Tiled/block pavement used to pave high traffic roadway?

Engineering decisions are fundamentally about problem solving. Thus, when asking, "Why not do [x] instead of [status quo]?" an answering question is: "What problem does [x] solve or ...

What is the type of pavement defect and how to address the issue?

My reputation is to low to comment but that looks like frost heave to me, does this area experience freezing temperatures? If it is frost-heave the answer is generally proper drainage and replacing ...

How to use MERRA data in Pavement ME Version 2.6 for rigid design?

The rigid calibration factors were not calibrated using the MERRA climatic data set. The application will automatically require NARR climatic inputs when rigid designs are selected. You can bypass ...

Per the ME Pavement Design Guide MOP, Section 5.3.6, Eq 5-18b, how is p02 assumed if not entered in Pavement ME?

The MOP, equation 5-18b calls for p02, which the MOP describes as the "Percent passing the 0.02 mm sieve". I assume that this is the percent passing for the subgrade. The percent passing ...

Tiled/block pavement used to pave high traffic roadway?

The reason tiles or flagstone or any other finishing is not used for heavy trrafic areas is lack of strength and toughness. Even in the decks you have attached photos these tiles/ stones will crack ...

Why is the JPCP CTE default value in Pavement ME 4.9 when the ME Pavement Design Guide Manual of Practice recommends 5.5 for unknown?

The JPCP CTE values in the MOP seems to reflect the old default CTE values based on the AASHTO TP 60-00 test method. An error was found in the testing procedure which was corrected using the AASHTO T ...

Pavement Mechanistic-Empirical Design application (v2.3) - Rehabilitation Flexible Calibration Factors

The thermal cracking model in Pavement ME Design prior to v2.3 only considered the predicted transverse cracks for the overlay layer and not the transverse cracks that reflected through the overlay ...

How can we model a full depth reclamation (FDR) layer with emulsion (wet FDR layer) in a pavement design?

Please refer to the Manual of Practice for the Mechanistic-Empirical Pavement Design Guide (MEPDG). The following is an extract from that manual: Full-Depth Reclamation (In-Place Pulverization of ...

How can I use backcalculated modulus results from FWD testing to represent my existing condition using Pavement ME Design?

The FWD modulus results are an input for the existing asphalt layers. One value can be input and a grid is not necessary, as shown in your screenshot above. You should evaluate the backcalculated ...

How does Pavement ME Design handle climatic data?

Pavement ME Design checks to see if the pavement construction date is within the entered climatic data range. If it is, the analysis uses that date. If the pavement construction date is not included ...

Why do the distress values for Pavement ME Design for alligator cracking and thermal cracking for AC pavements seem to give incorrect results?

Note that you can change the reliability for total fatigue cracking and total transverse cracking which includes the cracking in the existing AC layer that reflects through the AC overlay and new ...

What's sort of "sidewalk" pavement is this?

Antivehicular ones. But also anti pedestrian, The goal is to keep pedestrians and people, bikers, etc off this section. Namely because if it should be in proximity to moving vehicles.
