A distressed road surface does not mean the pavement has failed.

The premiere of Season 3 is here.

In Episode 1 of Pavement Engineering 101, we open the new season by exploring how to assess pavement distress before selecting a rehabilitation strategy.

Visible surface defects show deterioration, but a distressed pavement is not necessarily on the verge of failure. Understanding whether symptoms point to functional service issues or deeper structural damage is essential to determining the correct intervention.

Watch Episode 1 of Season 3, then let us know:
Which surface defect is misinterpreted most often: the one that looks catastrophic, or the minor crack that hides a failing base?

Can a 100 mm Bitumen Stabilised Material (BSM) layer utilising 100% Reclaimed Asphalt match the structural performance of a mix blended with virgin aggregate?

A 3.3 km Cold In-Place Recycling (CIR) trial on a single-lane dual carriageway northeast of Kiel, Germany, evaluated two recycled material compositions under real-world field conditions.

Working over an existing 100 mm asphalt layer on a granular base, the project evaluated two structural formulations:

- Section 1 (1.1 km): 100% Reclaimed Asphalt (RA)
- Section 2 (2.2 km): Reclaimed Asphalt blended with 0–16 mm crushed stone

Cement was applied prior to recycling. The reclaimed materials were processed using a Wirtgen W240 CRi cold recycler, paved with a Vögele Super 2100-5i, and compacted using Hamm tandem and pneumatic tyre rollers to produce the BSM layer. The section was then surfaced with a 60 mm asphalt binder course and a 40 mm wearing course.

Loudon International provided technical support throughout the trial, focusing on construction monitoring, process optimisation, and technical collaboration between Strabag, Wirtgen GmbH, and the Schleswig-Holstein State Road Authority (LBV.SH).

Full Depth Reclamation (FDR) project in Dammam, Eastern Province, Saudi Arabia. The road consists of a dual carriageway with two lanes in each direction and serves as an access road to King Fahd International Airport.

Project Specifications:
- Total length: 13.2 km per carriageway
- Recycling width: 12.3 m per carriageway
- Recycling depth: 200 mm

The existing pavement structure comprises a thick asphalt layer, including an asphalt wearing course and asphalt base course, overlying a stiff and intact granular layer.

Cement is utilised to stabilise the in-situ material during the FDR process. The 200 mm rehabilitation depth incorporates both the asphalt and granular material. A Wirtgen WR240 is used to mix the cement, asphalt, and granular material to create a cement-stabilised layer.
