The Kazakhstan Road Research Institute (KazdorNII) has developed a departmental standard establishing unified requirements for the maintenance, operation, and repair of street and road network facilities in cities of republican significance. The document defines mandatory inter-repair intervals, warranty periods, and procedures for maintaining urban road infrastructure. Its implementation is expected to improve road quality, extend service life, and enhance traffic safety.

Until now, no unified requirements existed for inter-repair intervals and warranty obligations for urban street and road networks. The relevant parameters were determined separately within each individual contract, creating legal and organizational uncertainty during facility acceptance, subsequent operation, and the resolution of identified defects.

The new departmental standard establishes, for the first time, a unified approach to the maintenance, operation, and repair of street and road network facilities in cities of republican significance. The document sets out mandatory requirements for pavement inter-repair service life, warranty periods, and technical traffic control devices, and regulates the procedures for maintaining urban road infrastructure.

"The development of this standard is aimed primarily at establishing unified and transparent requirements for the operation of urban road infrastructure. For the first time, mandatory inter-repair intervals and warranty periods have been defined at the regulatory level for all key elements of the street and road network. This will ensure a consistent approach to assessing the quality of work performed, increase the accountability of contracting organizations, and, as a result, extend the service life of urban roads," said Fazylzhanova A., Acting Director of the Department of Regulatory and Technical Support at KazdorNII.

The standard applies to all key elements of the street and road network, including road pavements, bridge structures, road signs, barrier and pedestrian guardrails, streetlight poles, road markings, curbstones, and other street infrastructure elements.

One of the key innovations is the mandatory installation of a protective wear layer on road pavement during construction, reconstruction, and major or medium repair of streets. This layer protects the pavement structure from moisture and traffic loads, reduces the risk of premature surface deterioration, and extends its service life.

To prevent and eliminate winter road slipperiness, the standard provides for the use of anti-icing materials that comply with the requirements of KR ST 4036 (Kazakhstan National Standard). The use of sodium chloride as an anti-icing material is prohibited.

Particular attention is given to quality control of completed work during the warranty period. The document provides for scheduled facility inspections to enable timely identification of defects, determination of their causes, and their resolution by contracting organizations under their warranty obligations.

The introduction of the new departmental standard will mark an important step in improving the management system for Kazakhstan's urban road infrastructure. The unified requirements will help standardize approaches to street operation and repair, improve the quality of work performed, extend the service life of road facilities, and ensure a higher level of safety.
