Reconstruction works



Survey of composition and construction of road foundations, Road to Westpunt

At the instruction of MNO-Vervat, CEGE undertook this survey of the composition and construction of the road foundations of the Road to Westpunt, within the section from Grote Berg to the Soto exit (Curaçao). This is due to the intention to upgrade the road in the short term. The works were carried out in consultation with and according to the design of the government’s Public Works Implementation Organization (UOOW).

Traffic management measures were deployed during the works (partial road closure). Core drillings were made in the asphalt surface in 17 locations, after which bore holes to a depth of 70 cm were augured in the foundation material (diabase). The material released was analyzed further in the laboratory. The following properties were identified as a result:

  • Particle size distribution of the foundation material under the asphalt in accordance with NEN 2560
  • Hardness (crush factor) in accordance with NEN EN 1097-2
  • Description and classification of the bored-out material
