Eco-Friendly and Energy-Efficient Technologies at This Year's HAPA Conference

The Hungarian Asphalt Pavement Association (HAPA) held its 17th annual conference at the Ramada Aurora Hotel & Resort Lake Balaton in Balatonalmádi on 23-24 February 2016. The event’s main topics revolved around eco-friendly and energy-efficient technologies and testing procedures, along with trends in European standardisation.

A number of our colleagues prepared presentations for this year’s conference: together with the development engineer of MOL, Dr. András Geiger, Colas Hungária chief technologist Lajos Balog shared the latest experiences regarding asphalt mixtures prepared with rubber bitumen. The quality manager of Colas Északkő, László Ézsiás, held a presentation entitled The expectations of asphalt producers – opportunities for crushed-stone manufacturers, and the business-development manager of Colas Út, Ildikó Lancsák, delivered her speech on The “forgotten” emulsion.

Ildikó started her presentation with an international overview, calling attention to the recognition of emulsion – contrary to the Hungarian practice – in professional circles abroad. The pace of building entirely new roads shows a slowing tendency worldwide, because the majority of road networks have already been completed by now. As a consequence, the maintenance of existing pavements is becoming increasingly significant, and the focus shifted to prolonging the life span of roadbeds in order to postpone comprehensive reconstruction works as much as possible. The demand is growing for economical and environmentally sustainable solutions that enable experts to extend the life cycle of existing pavements. With relatively low-cost interventions performed in due time, expensive reconstruction or restoration jobs can be avoided, making this kind of pavement preservation
cost-efficient in both the short and long term. One of the keys to pavement durability is bitumen emulsion. Although the current use of emulsion in Hungary is limited to applications as an adhesive, the material has a much wider range of functions in store: it is also suitable for the preparation of surface coatings, fibre-reinforced coatings, cold pothole repair mixtures, as well as coloured coatings and slurry seals. Bitumen emulsion can also serve an excellent binder, as evidenced by the Novacol and Valorcol technologies. 

Ildikó has been in charge of emulsion-related business development strategies at Colas Út for one year. She is devoted to stretching out the life span of roads by propagating the broader application of bitumen emulsion.

Colas Employees' Study Tour at the CST
Several years of fruitful cooperation between Colas Hungária’s Technology Directorate and the Paris campus of Colas SA paved the way for another study tour in France.
Compaction days at Bécsi Road
Following an offer from Profi Bagger Kft. and Wirtgen Budapest Kft., we had the chance to master the operation of Bomag’s intelligent compaction system called Asphalt Manager and Hamm’s HCQ Navigator satellite-based documentation application as part of single-day trainings.
Tech day for designers at the Technology Directorate
On 10 February 2015, the Technology Directorate held another of its popular tech days – this time specifically for road designers. Due to the large number of confirmed invitations, we will have to devote at least another day to the programme, with a total number of 80 guests.
Colas at the Innotrends Exhibition
Organised by the National Innovation Office with the cooperation of numerous Hungarian organisations and professional backing from Design Terminal and HIPAVILON Hungarian Intellectual Property Agency, the country’s major international research-development-innovation conference and startup exhibition was held in Budapest’s Akvárium Klub on 16-17 October 2014.
Laboratory Suitability Test of Pothole Repair Mixes
As a common practice, a public procurement procedure is launched each year by Magyar Közút Nonprofit Zrt. for cold pothole repair mixes. The tender description specifies both bitumen emulsion mixes and storable (made with thinned bitumen or special binders), bagged materials having maximum grain sizes of 8 and 11 mm.
