A workshop and seminar on the feasibility of using cold mix asphalt in infrastructural road works was hosted by the Demerara Harbour Bridge Corporation (DHBC), under the auspices of the Ministry of Public Infrastructure (MPI), on Wednesday, at the Pegasus Hotel.
According to an MPI press release, the seminar was held in collaboration with WADA Material Specialists Limited, Danny’s Enterprises Company Limited (Trinidad) and Wirtgren (Germany).
Cold mix asphalt, which often functions as a patching material, differs from the frequently used hot mix asphalt since it requires less application due to its longer shelf life; is easier to employ and does not require much technical knowledge. TLA Premium Cold Asphalt distributed by Panama Asphalt Inc was showcased during the session.
Delivering the feature address at the seminar, Minister of Public Infrastructure David Patterson observed that the workshop was “timely” as the ministry is pursuing new methods to improve road infrastructure in remote locations of the country.
DHBC Chairman Rawlston Adams said despite the administration having dedicated monies towards road works, due to the issue of upkeep the MPI is seeking innovative, uncomplicated and affordable methods of maintenance.
He also indicated that the primary focus of the cold mix asphalt is to achieve “zero potholes” in road maintenance in remote areas not easily accessible by conventional means.
In response, Minister Patterson suggested that while there is no definite proof of the role potholes play in road accidents, the aim of “zero potholes” could be a potential link to the safety of road users. He urged other agencies under the MPI, such as DHBC, to seek other methods of upgrading Guyana’s motorways.
